CD74ACT652EN

Overview

The CD74ACT652EN is an octal bus transceiver and register manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features three-state outputs for effective bus management. The device integrates eight D-type flip-flops, allowing data to be latched from the A ports to the B ports upon clock activation. It utilizes a 24-pin Small Outline Integrated Circuit (SOIC) package with a standard 0.300-inch width. The component supports through-hole mounting and functions reliably across an extended industrial temperature range.

Feature Summary

• Integrates octal bus transceiver functionality with simultaneous data registration capabilities
• Provides independent output enable control for each transmission direction
• Features three-state outputs to facilitate efficient multi-driver bus architectures

Applications

• High-performance microprocessor systems requiring bidirectional data transfer
• Memory mapping applications involving address and data bus interfacing
• Control logic circuits utilizing registered bus transceivers

Procurement Notes

Verify the specific suffix 'E' confirms the PDIP-24 package configuration rather than surface mount variants. Confirm RoHS compliance status and check for lead-free manufacturing certifications. Ensure the ordering part number matches the exact pinout requirements for your PCB footprint design before finalizing procurement.

Selection Notes

Select this component when both transparent bus transfer and registered storage are required in a single integrated circuit. The ACT series offers faster propagation delays compared to standard AC counterparts while maintaining CMOS power efficiency. Verify that the system voltage aligns with the specified 4.5 V to 5.5 V operating range for optimal performance.

Part Context

This device belongs to the Texas Instruments 74ACT logic family, designed for high-speed digital applications. It serves as a bridge between microprocessors and peripheral devices, combining the flexibility of a bus transceiver with the stability of a register. The octal configuration allows for parallel data handling across wide buses.
